Definitions

  • the present invention relates to a safety headrest for a seat, especially a vehicle seat, said headrest being mounted, via a holding means, on the back support of the seat, said holding means allowing the headrest to be adjusted in height relative to the seat.
  • Safety headrests on vehicle seats primarily have the object of giving head support to drivers or passengers at extroardinary loads, e.g. loads occurring as a result of rapid changes in vehicle velocity. If a vehicle is involved in a collision from the rear, a person sitting in the vehicle is subjected to a so called whiplash effect, such as to cause the head of the person to be thrown backwards very rapidly relative to the rest of the body. This can result in serious injury, and it is customary to provide at least the front seats in a vehicle with safety headrests limiting said backward movement, with the intention of reducing this danger.
  • Such a safety headrest is usually arranged on top of the back support of the seat, either as an integrated part thereof or as a separate unit which can be connected to the back support.
  • Mounting a headrest on top of a back support involves certain disadvantages, however. In the first place, the rear view will be obstructed for the driver, and in the second place the forward view will be obstructed for possible back-seat passengers, who can experience this as a kind of confinement.
  • the headrests raisable and lowerable in relation to the seat. This kind of safety headrest is thus mounted on one or two vertical bars which are displaceable longitudinally in guides attached to the back support.
  • the present invention has the object of forming a safety headrest which is adjustable in height and which in combination with a conventional back support of a vehicle seat enables improvement of vision in the vehicle without inhibiting the head-supporting function of the headrest for somebody sitting in the seat.
  • the headrest has a web portion, from which a forward leg portion and a rear leg portion extend downwards, said leg portions embracing the upper portion and adjoining the front and the rear, respectively, of the back support, said headrest being lowerable to a position where the web portion comes into contact with the uppermost part of the back support.
  • the safety headrest provides a shock-absorbing shield also for loads from behind, and in addition allround vision in the vehicle is improved.
  • FIG. 1 and 1A are perspective view of a seat provided with a safety headrest according to the invention, showing the headrest in different positions,
  • FIG. 2 is a partial front view of the frame structures of a back support and a safety headrest.
  • FIG. 3 is a sectional view taken on the line III--III of FIG. 2, and
  • FIG. 4 is a sectional view to an enlarged scale, taken on the line IV--IV of FIG. 2.
  • a safety headrest 1 is mounted on the back support 2 of a vehicle seat 40.
  • Said headrest 1 can be used in a lowered position, as shown in FIG. 1, or in one of several raised positions, as indicated in FIG. 1A.
  • the headrest is mounted on the back support 2 via a holding means 41, which can be of a conventional type or of a kind to be described in more detail later.
  • the safety headrest 1 has a web portion 42 from which a forward leg portion 43 extends downwards at the front of the back support 2, and from which a rear leg portion 44 extends downwards at the rear of the back support 2.
  • the two leg portions 43 and 44 embrace the back support 2.
  • the safety headrest 1 is shown in a raised position and is adjustable in height by means of a remote-controlled adjusting mechanism 3.
  • the back support 2 is conventionally constructed and comprises two side members 4, of which only one is shown in the figures.
  • the upper ends of the side members 4 are welded to a sheet metal casing 5 comprising a rear and a front base plate 6 and 7 respectively, which are mutually joined by means of welding.
  • the rear base plate 6 is formed with two substantially vertical depressions 8 (FIG. 4) enabling the base plates 6 and 7 to be attached to each other along these depressions 8 to form a vertical channel 9 in the metal casing 5.
  • a guide sleeve 10 made from plastics material, for displaceably mounting a bar 11 rigidly attached to the headrest 1. Said channel 9, guide sleeve 10 and bar 11, are incorporated in the holding means 41.
  • the inventive safety headrest 1 comprises a frame structure 13 of sheet material. As seen in FIG. 3 said frame structure 13 has a cross-sectional shape essentially like an inverted U. Between a front and rear leg 14 and 15, respectively, there is an upper portion or web which is provided with two depressions 16, to which an angularly bent upper portion of the bar 11 is attached by means of welding.
  • the bar 11 extends between the legs 14, 15 of the frame structure 13, and, as previously mentioned, passes through the guide 10 on the back support 2.
  • the bar 11 is formed with a longitudinal, central, open slot 12, successively tapering from the downward end of the bar 11 and having vertical extension with parallel side edges to approximately three quarters of the length of the bar 11.
  • the back support 2 as well as the headrest 1 are conventionally provided with soft-upholstered covering 17,18, indicated by dash dotted lines in FIG. 3.
  • the legs 14, 15 of the frame structure 13, and thus the leg portions 43,44 of the headrest 1 embrace the upper portion of the back support 2.
  • a portion of the upholstery 17 of the headrest is in contact with a portion of the upholstery 18 of the back support 2, at both front and back, even when the headrest 1 is in its uppermost position.
  • the flexible cable 20 is displaceably arranged inside a cable tube 19.
  • the cable 20 comprises a core 21 of steel wires wound about each other, the core being surrounded by a helically wound heavier steel wire 22, the cable 20 thus having an appearance similar to that of a screw.
  • the lower portion of the cable tube 19 is rigidly connected to a housing 23, in which the cogged means 24 is attached to a shaft 25 rotatably mounted in the housing 23.
  • An operating wheel 26 is also mounted on said shaft 25, whereby the cogged means 24 can be rotated.
  • the housing 23 is by means of screws 27 attached to the lower portion of a side member 4 so that the operating wheel 26 is easily accessible.
  • the cogged means 24 meshes in the wire turns of the cable 20 in the same way as a pinion meshes with a rack.
  • the upper part of the cable 20 is rigidly attached to a fixing plate 28 running in a lengthwise slot 29 in the cable tube 19.
  • the fixing plate 28 is welded to an operating member 30, the upper part of which is provided with a stop 31 fitting into a recess 32 in the bar 11.
  • the operating member 30 provides spring bias for retaining the stop 31 in the recess 32. This spring bias also results in that the bar 11 is pressed into engagement against the front wall of the guide sleeve 10, thus nullifying possible play between the sleeve 10 and the bar 11.
  • the upper end of the cable tube 19 is intended to fit into the vertical, open slot 12 in the bar 11.
  • the operating wheel 26 is turned, the cable 20 thus being displaced longitudinally in the cable tube 19 to actuate the operating member 30 and the bar 11 for a corresponding travel.
  • the cable 20 and the cogged means 24 in the housing are preferably formed to have a self-locking action, known per se.
  • the described mechanism 3 for adjusting the height of the headrest 1 requires little space, resulting in that it is not necessary to increase the thickness of the back support 2 to accommodate the controlling mechanism therein, in case it is desired to use remote control of the headrest.
  • the described safety headrest 1 can of course also be used for seats not equipped with a remote-controlled adjusting mechanism.
  • the headrest can thus be given a fixed position or be conventionally mounted on a holding means allowing positioning of the headrest at different heights by direct manual action on the headrest.
  • Such holding means are previously known and need therefore not be described in detail.
  • Positioning of the headrest at various heights could be facilitated by using spring means or the like snapping into notches or the like in the guide sleeve 10 or on the bar 11 and by deleting the equipment shown in FIGS. 2-4 for operating the bar 11.
  • Other modifications, with or without an adjusting mechanism for controlling the height of the headrest, would be possible within the scope of the appended patent claims.
